What do you do now? (Table Issue)

[CA BBall Ref]

1:27 Left in the fourth, visitor down by 4. Jump ball on the floor. Arrow points to visitor. Ready to inbound when scorekeeper blows the horn. Go to the table and official scorekeeper insists that the arrow is wrong. Should be to the home team. My partner and I huddle quickly and discuss and are fairly sure that the arrow is correct. Scorekeepers says there was another jump ball at the 3:07 mark. I look at the visitors book & it is identical to hers except for this last jump ball. My partner & I are 95% sure but not 100% that the arrow is correct. I go with the arrow and she is screaming my book is the only official book. Fortunately Home won in overtime and all is well. Without being 100% sure of you arrow what would you do?
P.S. It no no longer matters if the powers that be say not to keep the arrow in you pocket, I will be from here on out.
